Every U-2 flight requires a lot of behind the scenes work. An assortment of engineers, technicians, and flight line personnel line up to support every mission. The high altitudes at which the Dragon Lady operates, however, create a unique set of responsibilities for ground support personnel. Many of these responsibilities fall on the shoulders of life support technicians.

The U-2 gathers imagery in a number of ways, including through digital imagery, radar imagery, and traditional wet-processed film. Similarly the U-2 collects signals intelligence in various frequency bands with a variety of sensors. Datalinks on the aircraft allow for immediate transmission of sensor data. The U-2 carries an electronic countermeasure system for self-defense.

Thirty-four U-2s are flying today. Most were built in the 1980s as TR-1s though a few are U-2Rs built in the late 1960s. All of these aircraft were re-designated U-2S in 1999, with two exceptions. The two-seat trainer version, accounting for five airframes, is referred to as the TU-2S. The NASA version, accounting for two airframes derived from the U-2S, is referred to as the ER-2.

The U-2 high-altitude reconnaissance aircraft continues to serve as America’s Sentinel of Peace. Current U-2s are equipped with the latest, most advanced signals intelligence, measurement and signature intelligence, and imagery intelligence sensors in the Air Force inventory.

Now, the U-2 carries imaging and signals intelligence sensors that are as sophisticated as any in the US inventory. Over Iraq during Desert Storm, then over Bosnia, Kosovo, and most recently over Afghanistan, these high-flying eyes and ears have proved indispensable. In the obscure world of aerial reconnaissance, most of the attention, and most of the praise, has gone to other platforms.
